6470 points – EVGA GeForce GTX 480
5420 points – ATI Radeon HD 5870
5161 points – MSI GeForce GTX 470
4693 points (Avg FPS: 78) – SAPPHIRE Radeon HD 6870, GPU core: 1020MHz

Remark: the score with a 1020MHz GPU is given only for the fun. Stressed by FurMark in Xtreme mode, the GPU clocked at 1020MHz is not stable (freeze).


3.2 TessMark (OpenGL 4)

Hardware tessellation is one of the big features of Direct3D 11 and OpenGL 4 capable graphics cards. TessMark is a new benchmark focused only on the tessellation engine of DX11 class cards. It’s a pure tessellation benchmark, it does not contain complex shader or other heavy texture fetches. TessMark shows an overview of the tessellation engine raw power, that’s all. DX11 specifies that the tessellation factor can vary from 1.0 up tp 64.0. Of course, for tessellation factors like 32 or 64, most of the tessellated triangles are smaller than… a pixel. In those cases, tessellation is useless and in a real world application such as a game, high tessellation factors won’t be used. But in the case of a synthetic benchmark, it’s always instructive to see how cards can handle the whole range of tessellation level.

TessMark 0.2.2 has been used for the test.

Settings: 1920×1080 fullscreen, no AA, 60sec, map set 1.
